' Harvester Cutter. v

Patentd March 18, 1856.

the city of Quincy, county of Adams, and State and use my invention, I will proceed to describe NITED STATES IMPROVEM ENT IN, HARVESTER-CUTTERS.

Specification forming part of Letters Patent No. 14,453, dated March 18, 1856.

'10 all whom it may concern:

Be it known that I, I'lORACE L, HERVEY, of

of Illinois, have invented a new and useful Im provement in Grain, Grass, Hemp, and Flax Harvesters; and I hereby declare that the following is a lull and exact description thereof, reference being had to the accompanying drawings, and toletters of reference marked thereon.

Figure 1 is a section showing a perspective view of the improvement. Fig. 2 is a section showing one of the blocks containing a slot and inclined planes. Fig. 3 is an end View of the same block. Fig. 4 is a View of one of the arms of the cutting-bar provided with frictionrollers. Fig. 5 is a view of a stalk of grain, showing the manner of cut-ting it off.

To enable others skilled in the art to make its construction and operation.

In the construction of my invention, Fig. 1, letter A represents the knives or cutters; B, the floor for the purpose of receiving the grain. Cis the cutter-bar; D, the cutterbar arms working in the slots, and are provided with friction-rollers to work upon the inclined planes contained in the blocks E. E are the blocks, provided with slots to guide the cutter-bar.

Fig. 2 is one of the blocks E for the arms to work in, and is provided with slots for'the purpose to guide the cutter and for the arms D to work in. It is also provided with inclined planes 2 for the friction-rollers to move upon.

Fig. 3 is an end view of the block E. Fig. 4 is a view of one of the arms of the cutter-bars C, and is provided with the friction-rollers a b on end of cutter-bar C.

planes are set at or near an angle of forty-fivedegrees, or any angle between a horizontal line and the above given angle.

In the operation of my machine the bar C, by the means ot the inclined planes in blocks E and friction-rollers d, is made to move at an angle from a horizontal line'when it is moved backward and forward, and by that means is made to cut the grain off at an angle, as is rep- I resented at b in Fig. 5. v

1 may find in the use of my cutters that a straight knife or cutter may be used, placing it on a straight cutter-bar, the cutter-bar operating as described herein, thereby giving to the knife the inclined out, which is the great point in my invention which I desire to secure.

Having described the construction and operation of my invention, whatl claimas new, and desire to secure by Letters Patent, is

Furnishing the cutter-bar with a series of inclined blades or knives, in combination with the inclined blocks E and rollers 61, or their equivalents, for giving to said cutters or cutter-bar an oblique cut.
